Why yes Fish, rode mine to work this morning in 25F temperature. I can't really give a whole appraisal yet as I only have 4200 miles on it so far. To date, I had the TPS adjusted first week 9engine kept dying when I rolled the throttle off), and a fog light replaced at 900 miles or so, no other mechanical issues. I have discovered the rev limiter in first through third gear is a pain in the bum and that ABS really does work (riding around the DC area, I get to exercise it several times a month it seems). I have ridden all day single and two up with no worries at all either on the flat lands or up on Skyline Drive in the low mountains. I have ridden in a slow moving parade with no worries (again, riding around the DC area, one gets lots of practice riding/walking the bike in stop and go traffic). I will soon add Tors and a K&N air filter but probably won’t do any other mods till after the warranty goes out.
Since I haven’t ridden in hot weather, I have no point to compare there. But as for cold air, the bike loves to take long deeps breaths of it! I hope this helps some.
